The bucardo became extinct in 2000, but cells from the last animal were frozen in liquid nitrogen. In 2003, a cloned calf was brought to term but died a few minutes after birth. Now, the scientists will test the viability of the female bucardo's 14-year-old preserved cells. The bucardo, or Pyrenean ibex, calf born through cloning was an historic event: the first "de-extinction", in which a lost species or sub-species was resurrected.

Biologists briefly brought the extinct Pyrenean ibex back to life in 2003 by creating a clone from a frozen tissue sample harvested before the goat's entire population vanished in 2000. The clone survived just seven minutes after birth, but it gave scientists hope that "de-extinction," once a pipedream, could become a reality. Ten years later, a group of researchers and conservationists gathered in Washington, D.C., today (March 15) for a forum called TEDxDeExtinction, hosted by the National Geographic Society, to talk about how to revive extinct animals, from the Tasmanian tiger and the saber-toothed tiger to the woolly mammoth and...
